had my superchip tuner on my 03 5.7 for a while and i tuned it back to stock for winter all the time and the last time i go to tune it back it wont tune out the tmr... it always use to but it stopped doin it now. I got myself a bullydog triple dog and since then have done the tmr delete and it seems waaay better but why would it stop working in the first place?

 

because a superchips tuner cannot overwrite the Bullydog tuner.... you have to take the Bullydog off before you connect the superchips... no?

Unless I'm misunderstanding something.....

 

lol ya i no i obviously tuned it back before i did it not sure how it would work trying to do it while ur stock tune file is on ur other tuner. not sure why the superchips stopped working but my new tuner is beast wit the tmr delete
